1. Hammer dowel pins (right and left) into their original positions in

the front timing chain case up to a point close to taper in order to

shorten protrusion length.

NOTE:

Be sure to place the dowel pins in original hole locations in the

front timing chain case. 

2. Install new front oil seal on the front timing chain case.

• Apply new engine oil to both oil seal lip and dust seal lip.

• Install it so that each seal lip is oriented as shown. 

• Press-fit oil seal until it becomes flush with front timing chain

case end face using suitable drift [outer diameter: 60 mm (2.36

in)].

• Make sure the garter spring is in position and seal lip is not

inverted.

CAUTION:

• Be careful not to damage front timing chain case and

crankshaft.

• Press-fit straight and avoid causing burrs or tilting oil

seal.

3. Install water pump cover and chain tensioner cover to front timing chain case, if removed.

• Apply a continuous bead of liquid gasket using Tool to front

timing chain case as shown.

CAUTION:

• Remove water, oil, dust, dirt, or other foreign material on

all sealing surfaces prior to installation. 

• The components must be installed within 5 minutes of

the liquid gasket application. Then allow 30 minutes for

the liquid gasket to set before operating the engine.

• Use Genuine RTV Silicone Sealant or equivalent. Refer

to 

GI-14, "Recommended Chemical Products and Seal-

ants"

.

4. Install idler pulley, if removed.
5. Install front timing chain case as follows:

FRONT TIMING CHAIN CASE

a. Apply a continuous bead of liquid gasket using Tool to front tim-

ing chain case back side as shown.

CAUTION:

• Remove water, oil, dust, dirt, or other foreign material on

all sealing surfaces prior to installation. 

• The components must be installed within 5 minutes of the

liquid gasket application. Then allow 30 minutes for the

liquid gasket to set before operating the engine.

• Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

b. Install new O-rings on rear timing chain case.

CAUTION:

Do not reuse O-rings.

c.

Assemble front timing chain case as follows:

i.

Fit lower end of front timing chain case tightly onto top face of oil

pan (upper). From the fitting point, make entire front timing chain

case contact rear timing chain case completely.

ii.

Since front timing chain case is offset for difference of bolt holes,

tighten bolts temporarily while holding front timing chain case

from front and top as shown.

iii. Same as the previous step, insert dowel pin while holding front

timing chain case from front and top completely.

b. Apply a continuous bead of liquid gasket using Tool to intake

valve timing control covers as shown.

CAUTION:

• Remove water, oil, dust, dirt, or other foreign material on

all sealing surfaces prior to installation. 

• The components must be installed within 5 minutes of the

liquid gasket application. Then allow 30 minutes for the

liquid gasket to set before operating the engine.

• Use Genuine RTV Silicone Sealant or equivalent. Refer to

.

c. Install new collared O-rings in front timing chain case oil hole

(left and right sides).

CAUTION:

Do not reuse O-rings.

d. Being careful not to move seal ring from the installation groove, align dowel pins on front timing chain

case with the holes to install intake valve timing control covers.

e. Tighten bolts in numerical order as shown.

8. Install crankshaft pulley as follows:
a. Install crankshaft pulley, taking care not to damage front oil seal.

• When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).

b. Tighten crankshaft pulley bolt in two steps.

c.

Remove Tool to release the ring gear and install the rear cover. Refer to

.

9. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns

smoothly.

10. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to 

MA-18, "FOR USA AND CANADA : Fluids and Lubricants"

 (United

States and Canada) and 

MA-20, "FOR MEXICO : Fluids and Lubricants"

 (Mexico).

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-

ified level, if necessary.

• Summary of the inspection items:

*Power steering fluid, brake fluid, etc.

CAUTION:

• After removing timing chains, do not turn the crankshaft and camshaft separately, or the valves will

strike the pistons.

• When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting

surfaces with new engine oil.

• Apply new engine oil to bolt threads and seat surfaces when installing camshaft sprockets, camshaft

brackets, and crankshaft pulley.

NOTE:

It is not necessary to remove the rocker covers or intake manifold collector to remove or install the timing

chain(s).
